Claims (1)

[Claims for Utility Model Registration] A part that uses a motor to drive a mechanism that changes the angle of depression of a transducer that detects underwater conditions by emitting ultrasonic waves into the water, and the actual value of the angle of depression (hereinafter referred to as the actual angle of depression). a part that detects the depression angle, a part that sets the depression angle to a required angle and displays the set required angle, a signal obtained by the detection (hereinafter referred to as a detected depression angle signal), and a signal obtained by the setting (hereinafter referred to as a transducer/receiver pointing direction control device having a part that drives the motor based on a set angle of depression signal (referred to as a set depression angle signal); (b) digital signal generating means for generating a digital signal by operating the angle setting means; (c) converting the digital signal into an analog signal using a DA converter to perform the setting. AD means for obtaining a depression angle signal; d) an inclinometer in which a permanent magnet is attached to a shaft that rotates based on the actual depression angle and a magnetic flux detection Hall element is provided within the rotation range of the permanent magnet; an actual depression angle detection means for detecting an actual depression angle.
